Resources

OSU has many publications available online. Most of these are in PDF format, so they can be read online, bookmarked for later reference, or downloaded and saved to your own device. Publications specifically geared to the home gardener have been collected into a single list (all hyperlinks) for your convenience.

An amazing variety of common plants are toxic, either to humans or animals. UC Davis has an extensive list that includes both ingested and contact toxicity for people. And to keep your pets safe, check out the ASPCA list of animals toxics. You can click on the “View by” link to toggle between common and scientific plant names.

Clackamas Co. Master Gardeners have developed an educational series called the 10-Minute University. This includes both written material and videos on many aspects of home gardens, which provide reliable information to help you enhance your gardening skills.

These are only a very tiny fraction of the resources you’ll find online. We strongly recommend that you focus on research-based information (domains .edu and .org). Many of the “helpful hints” sites do indeed offer suggestions that will address a specific problem, but they often overlook undesirable aftereffects. One common example is using table salt to kill slugs. Yes, the slugs will be dead. But your soil will be contaminated by the salt, and it’s apt to cause problems for your plants.
